Unverified-Licorice/half sugar version ink screen reader sd card version

Overview

Modify the PCB of Licorice and Bansu, adding the BL/RX8025 clock chip (Halfsugar) and TF (microSD) card slot (Licorice/Halfsugar), without deleting other peripherals. Test 0 and Test 1 are used below. Picture card slot.

The difference is that the direction is different. Since the SD card will protrude after being inserted into the card slot, it is impossible to determine whether it will exceed the edge of the board. Therefore, two versions are provided, which are suitable for use with cases without gaps. To replace the SD card, you need to open the case.

Both test 2 and the half-sugar version use the following card slots. In test 2, there is a high probability that the SD card will exceed the edge of the board after being inserted. It needs to be used with the notch in the shell to facilitate the removal and insertion of the card.

I am just an electronics amateur. The PCB is drawn exactly according to the schematic diagram. There may be electrical defects in the wiring. Please check carefully and proofing with caution.
